Q

How does the anatomy of the pulp make it more prone to infection?

A
  • Surrounded by hard dentin which limits its ability to expand (if an infection is present the pulp is not able to expand against the hard dentin surrounding it)
  • Lacks collateral circulation which limits its ability to cope with infection (one way in and one way out) - less avenues for immune cells to get into the pulp to help
